Quick question...

[gassafe]

Gotta quote replacement trvs... like for like, all currently on microbore plastic with those collapsible internal brass reducers which I don't normally rate!

Is it okay to re-use the these fittings or isn't that asking for trouble... don't want to have to add couplers on all of them as it would look a mess!

Thanks

If it's the one piece brass ones, in my opinion I don't rate these and it is the chance you take. I've had these leak from new.
The 3 piece ones with the olive in the middle are as good as you get for internal reducers. If it's them, then jet blue it as you go, should be fine.

if one piece i wouldnt use them again i have always found them ok always wrapped pt. around the gap so when it splits as you tighten its helps the seal. i would fit new olive/ reducers

One of these good ideas on paper.
But Fails in practice.

Ptfe and they'll be OK

If they're 15 x 10 what about a Push fit spigot reducer, it may give you some length without adding a coupler.
Can't see any 15 x 8 tho'

It's the drayton 1 piece collapsible ones onto 8mm plastic I believe, think I'm gonna have to brace it but there's about 15 to do

should be a nice little job pricewise then 15 trvs

Only if those little reducers play ball lol

I tend to take some yorkshire reducers ( they are longer) and cut the microbore, solder on and replace with a 15mm valve.

You sure it's 8mm plastic and not 10mm? Don't think I've ever seen 8mm plastic, is that a thing?
I hate those collapsable reducers bloomin horrible idea, I'd be 'too busy' unless there's scope to redo all the pipe ends, if the pipes come up from under the floor you're laughing.

I normally do that but less options on plastic... pretty sure it's 8mm grey plastic
